Design Pattern Video

This demo of the TwoUse Toolkit shows how we integrate UML, OWL and SPARQL to dynamically classify instances at runtime. We show how to model the variations of the class SalesOrder with OWL, namely USSalesOrder and GermanSalesOrder. Later, we write a query operation that asks for the most specific type of the contextual object. More information about the TwoUse Toolkit on twouse.googlecode.com
